Dear all, I'm currently trying to have a popup tooltip show over my main Open GL window. Naturally my Open GL window is constantly painting but I registered it as a WS_CLIPCHILDREN and WS_CLIPSIBLINGS style and subsequently my tooltip as a WS_CHILD window to this window. Even though I've done this, my tooltip is almost immediately painted over...? Similarly I have some owner drawn button controls in my window that do not get painted over although are registered in a similar fashion as children. Can anyone think perhaps of an easy way to work around this or where I may be going wrong? Kind Regards, James

Do yourself a favor and make your own tool tips with OpenGL unless they're to be rendered outside of the OpenGL window.

Thanks for the replies, I'll probably try both and see which works out best.

Regards
